Hashem

HaShem (, often abbreviated to [''h′'']) is a title used in Judaism to refer to God.

In Judaism, ''HaShem'' (lit. 'the Name') is employed to refer to God when not in prayer, in which the term ''Adonai'' ("''my master''") is used. This is to avoid pronouncing God's name casually, a practice rooted in one of the Ten Commandments.

Maimonides writes:

This led to God's name being replaced with the title, Hashem.

A popular expression containing this phrase is Baruch HaShem, meaning "Thank God" (literally, 'Blessed be the Name'). Provided by Wikipedia
